\Delta=m^2-4\cdot2\cdot8=m^2-64\\
m^2-64\ \textgreater \ 0\\
m^2\ \textgreater \ 64\\
m\ \textgreater \ 8 \vee m\ \textless \ -8\\

Determine the coordinates of the point $P$ on the line $y=-x+6$ such that $P$ is equidistant from the points $A(10,-10)$ and $O(

lidiya [134]

Answer:

P=(3,3)

Step-by-step explanation:

We need to find a point P in the line $y=-x+6$ such that $PA=P0$ where $A=(10,-10)$

Observe that the coordinates of P are $(x,y)=(x,-x+6)$ because P is in the line.

Then,

$PA=P0\\(x,-x+6)(10,-10)=(x,-x+6)(0,0)\\10x+(-x+6)(-10)=0\\10x+10x-60=0\\20x=60\\x=3$

We reeplace the value of x in the coordinates of P and obtain the point

$(3,-3+6)=(3,3)=P$

A quadrilateral has exactly one right angle and two nonadjacent angles that each measure 105 degrees

LiRa [457]

Answer:

C) Kite

Step-by-step explanation:

The problem states that the polygon is a quadrilateral, meaning it has 4 sides. This rules out D, as pentagons have 5 sides. Our next clue is that this shape has <em>only one </em>right angle, ruling out A and B, because, by definition, rectangles and squares must have four 90 degree angles. We can already see that we are left with only one choice, but to confirm: a kite has 2 opposite angles of 105 degrees, like the problem states.

Therefore, the answer is C) Kite

Hope this helps!
